HVAC Contractor Funding for Residential, Commercial and Mechanical Contractors

Banks underwrite HVAC contractors on the wrong shape of cash flow. A bank looks at twelve months of financials and sees a business that made most of its money in July, August, January and February and lost money in April and October, and it prices that as volatility rather than as the normal HVAC calendar. The collateral is weak from a bank's perspective: vans, recovery machines, gauges and inventory depreciate fast, and the largest asset most shops have is a book of maintenance agreements that a bank does not know how to value. Timing is the bigger problem. A bank line takes weeks to open and cannot be increased in the middle of a heat wave, which is exactly when the supply house wants payment before releasing equipment that is on allocation. Many owners came up through the trade, bought the business or started it with personal credit, and carry a prior equipment default or a tax lien from a slow year, which is an automatic decline at most banks regardless of current deposits.

Revenue-based funding underwrites on the deposits an HVAC business is actually producing, so the July surge counts for what it is instead of being averaged against the April trough, and a prior credit event does not end the conversation. It arrives in days, not weeks, which matters when a distributor releases A2L stock to accounts that pay now. Remittance is a fixed percentage of revenue collected by ACH, so a $40,000 January and a $140,000 July remit in proportion to what came in; that matches the HVAC calendar in a way a fixed monthly bank payment never does.

It also fits what the business owns. We underwrite on bank deposits and revenue patterns rather than credit score or hard collateral, which suits a company whose assets are depreciating vans, recovery machines and vacuum pumps rather than real estate. HVAC contractors use this capital to stock equipment and refrigerant before the first heat wave, to pay overtime and per-diem when a cold snap fills the board, to buy or upfit a service van when a new tech is hired, to carry a commercial receivable without turning down the next bid, and to make payroll through the trough every HVAC business has. A merchant cash advance is not a loan; it is the purchase of future receivables. Not all applicants qualify, and approval depends on revenue patterns, deposit consistency, time in business, existing obligations and other factors.

Daily or weekly ACH remittance set as a percentage of revenue, so remittance flexes with actual service and install volume. Total terms typically range from 6 to 18 months depending on advance size and deposit consistency.

Two peaks and two troughs. Cooling demand builds from the first sustained heat, usually late May in the South and late June in the North, and the first week of a heat wave produces more no-cool calls and emergency change-outs than a normal month; heating demand starts with the first hard freeze and runs through February. The shoulder months (roughly March-April and October-November) carry service and maintenance-agreement work but few replacements, and they are when payroll is hardest to cover. Fall tune-up season compresses a year of maintenance-agreement labor into about six weeks. Commercial and new-construction work follows the building cycle rather than the weather, which is why a mixed residential-commercial shop has smoother deposits than a pure residential one. Regional efficiency rules also matter: since January 1, 2023 residential AC has been rated in SEER2 with different minimums for the North, Southeast and Southwest, so the equipment a Texas contractor stocks is not the same SKU an Ohio contractor stocks, and a supply house in each region carries different inventory into each peak.

State and local mechanical contractor licensing, with bonding and insurance requirements that vary by jurisdiction; EPA Section 608 technician certification for anyone who handles refrigerant; the AIM Act HFC phasedown, which cut off manufacture of R-410A residential systems on January 1, 2025, moved the industry to A2L refrigerants (R-454B, R-32), and steps the legal HFC supply down again on September 30, 2026; EPA's July 27, 2026 rule that removed the federal deadline for installing already-manufactured R-410A systems (window units still cut off January 1, 2028), versus New York's state law that kept the January 1, 2026 install ban; DOE 2023 minimum efficiency standards expressed in SEER2, EER2 and HSPF2 with regional minimums for the North, Southeast and Southwest; A2L-specific code requirements for leak detection and installation practices in the current mechanical codes; permit and inspection requirements on replacements and load calculations (Manual J) where the AHJ requires them; OSHA rules on rooftop, attic and confined-space work; refrigerant recovery and reclaim rules.
